I called up Midway Services to put in a couple of water lines in two different homes for myself and my niece. We also used them to install some air conditioning units. The HVAC and plumbing professionals that they send out are always professional and good fellas to work with. Everything always comes out working great. Recently I needed a 5 inch filter for my air conditioner, I went to Home Depot and some other places but they didn't have them. It was a relief to call Midway Services and hear that they supplied the filters in that size. I will call them again in the future!
